Repair at insignificant damages of body details
Elimination of small scratches
If scratch superficial also does not mention metal of the body panel, its repair is carried out extremely simply. For removal of particles of the lagged behind paint and a wax covering slightly rub the scratched area with thin grinding paste. Rinse the processed surface with pure water.
Small brush paint over scratch paint for external panels of a body. Continue to put paint a layer behind a layer until the surface in scratch will not reach level of a surrounding surface of a paint and varnish covering of the panel. Give to new paint полимеризоваться within at least two weeks, then polish a transitional surface aflush with a surface of a covering of other part of the panel with application of the thinnest grinding paste. In summary cover the processed surface with wax.
If scratch got through a paint coat, having reached some metal of a body and having caused its corrosion, it is necessary to apply other technology of repair. A penknife scrape out from scratch a poroshkoobrazny rust, then process a surface corrosion inhibitor in order to avoid development of the centers of corrosion in the future. With a rubber or plastic shpatel cover the processed
inhibitor the damaged area a shpaklevka. If necessary, and it is especially useful at a shpaklevka of narrow scratches, for formation of melkodispersny paste it is possible to dilute a shpaklevka with solvent. Before the shpaklevka will harden in scratch, wrap up a finger-tip a smooth cotton fabric. Then, having moistened a finger in solvent, quickly carry out them along the puttied surface of scratch — it will make a surface slightly concave. Now after shpaklevka hardening the processed scratch can be painted according to the instructions provided for cases when scratch does not mention metal.
Repair of dents
At repair of dents by a priority the pulling of the deformed surface for the purpose of its removal to initial level is. Attempts to achieve absolute compliance to the original have no sense as it is all the same impossible in view of violation of internal structure of metal of the body panel at blow. Removal of a concave surface to level approximately on 3 mm lower than a surface of the surrounding intact site of the panel of a body is optimum. If the dent superficial, its full pulling at all has no sense.
In a case when to a concave site it is possible to reach from a reverse side of the panel, it is necessary to try отрихтовать a dent from within in hammer blows with brisk of a soft material (rubber, plastic). Tapping a dent, densely press to its face a wooden hammer for blow clearing in order to avoid an excessive flexure outside of the deformed metal of the panel.
If the dent was formed on a two-layer site of the panel or access to it from a reverse side is impossible for any other reason, it is necessary to apply other technique of a pulling. Make in a concave site of the panel some small openings, trying, that they appeared in the most zaglublenny areas of a dent. Then screw in openings long self-cutting screws, having left their heads sticking out so that it was possible to grasp them пассатижами. Now start to extend a dent nippers for screws.
At the following stage of processing of a dent it is necessary to remove from the damaged surface and on a site in width about 3 cm round it the remains of a paint and varnish covering. This work is best of all for carrying out by means of a wire nozzle or the zachistny disk established in a cartridge of an electrodrill, also processing by an emery paper manually however is not less effective. The final stage of preparation for a shpaklevka — a protsarapyvaniye cleared of paint
dent metal a screw-driver or a fragment of a file or drilling in it small openings for ensuring the maximum adhesion of a shpaklevka to a metal surface. Further it is possible to pass to shpaklevka and coloring performance.
Repair of through corrosion damages and holes
By means of the shkuryashchy or wire nozzle clamped in a cartridge of an electrodrill, remove all traces of paint from the damaged area and on a site in width about 3 cm round it. In case of lack of possibility of use of an electrodrill work can be executed not less effectively by an emery paper manually.
After removal of paint it is possible to estimate a metal damage rate corrosion and
to define, whether there is a sense to start repair or it will be more reasonable to replace completely the panel (if it in principle is possible). New panels can be got not too expensively as many motorists consider. Often it appears much quicker and even to establish the new panel more economically, than to repair extensive damages of a body.
Remove from the damaged panel all elements of furnish of a body, except for what can serve as a reference point for a reconstruction of an original form of the deformed sites (such as facing of block headlights, etc.). With scissors on metal or a nozhovochny cloth remove everything sites of metal freely dangling, poorly fixed and hopelessly damaged by corrosion. Then unbend a hammer of edge of an opening inside for formation of deepening which will be filled with a shpaklevka.
By means of a metal brush remove from the damaged metal a poroshkoobrazny rust. If there is an access to a reverse side of the damaged site, process it corrosion inhibitor.
Before the beginning of a shpaklevka muffle an opening. It can be made, приклепав or having tightened to the damaged site from its reverse side a piece of a tin or having blocked an opening a wire grid.
After the opening will be closed, the damaged site can be puttied and painted.
Shpaklevka and coloring
The set of body shpaklevka is issued, however it is necessary to notice that for works of this kind enclosed to sets shpaklevochny paste best of all is suitable for repair of body panels with a hardener. To reach smoothness and correctness of a contour of the puttied surface, it is necessary to put paste with a flexible plastic or nylon shpatel. Strictly following instructions of the producer of a shpaklevka (violation can lead to the wrong hardening of shpaklevochny weight), mix insignificant quantity of a shpaklevka on a pure wooden or cardboard surface (carefully use a hardener).
With Shpatel put a shpaklevka on previously prepared surface of the damaged site of the body panel. For achievement of a desirable contour of a surface and shpaklevka level each dab a shpatel should pass through all repaired surface. As soon as the contour of the puttied surface becomes close to demanded, immediately stop to put a shpaklevka as it, stiffening, will begin подлипать to a shpatel, forming lumps and leaving вырывы on a processed surface. Continue to put paste layers with intervals about 20 mines until level of the puttied surface will not begin to act slightly over surrounding metal of the panel.
After shpaklevka hardening it is possible to remove its surplus with a file. The stage of a zashkurivaniye and polishing of the puttied surface further begins. Best of all the waterproof emery paper is suitable for this purpose. It is necessary to begin with coarse-grained paper No. 180 and further, consistently reducing granularity, to finish No. 600. To reach adequate planeness of a processed surface, it is necessary to wrap up previously paper round whetstone from dense rubber (a tree or polyfoam) or to paste on it. In the course of processing it is necessary regularly and to moisten paper with water often. Such technology allows to receive absolutely smooth and equal processed surface at the final stage.
The processed surface should appear surrounded with a ring of pure metal which comes to an end with gradually coming to naught paint coat. Wash out the processed surface pure water, washout from it all dust formed during polishing.
From an aerosol ballonchik with a thin layer put on the processed surface a layer of a light first coat, a so-called pro-attendance layer. It will allow to reveal all defects allowed during polishing which can be eliminated with a pokryvaniye way their new layer of a shpaklevka. Repeat a zashkurivaniye and polishing. Repeat a shpaklevka, processing and a surface first coat before receiving satisfactory (on quality of the received surface) result. On termination of wash out the processed surface water and dry up it.
Now the surface is ready to coloring. Car coloring from an aerosol ballonchik should be carried out at motionless, dry, warm and not dusty air. Most fully meet these requirements of a condition of the spacious closed and heated room. If circumstances
compel to carry out body coloring in the open air, it is necessary to treat a choice of suitable weather conditions very seriously. At work indoors remove a dust, having sprinkled a room floor water. If painting only one panel of a body of the car is carried out, cover the intact panels surrounding it. This precautionary measure will allow to minimize effect of insignificant difference in tones of old and new paints. Such elements of furnish as the chromeplated decorative strips, etc., also it is necessary to cover door handles (and it is better to remove absolutely). For protection of surfaces not subject to coloring use a special sticky tape (a painting adhesive tape) and old newspapers which should be imposed in some layers.
Before starting coloring from an aerosol ballonchik, carefully stir up it, then put paint on a trial surface, fulfilling equipment of coloring. Cover the surface prepared for coloring with a layer of earth. The demanded thickness of a layer is reached at the expense of repeated drawing of soil by thin layers. Without feeling sorry some water, a moisture resistant emery paper No. 600 process the grounded surface, achieving its absolute smoothness. Before starting final coloring let's to soil dry completely.
Put a paint coat, again achieving the demanded thickness at the expense of its repeated drawing. Coloring begin from the center of a repaired site; making a hand with a ballonchik roundabouts, increase their radius, moving on a spiral until there will be covered all damaged area and a part of an old paint and varnish covering for the width about five centimeters. Later 10–15 mines (not later not to damage edge starting to stiffen fresh paints) after drawing of the last paint coat separate covering surrounding panels of a body of the newspaper and a sticky tape. Paint finally полимеризуется within about two weeks then for transition smoothing from fresh paint to put earlier process the restored surface the thinnest grinding paste. In summary put on the panel a layer of a protective tool with wax.
Repair at considerable damages of a body
Repair of serious damages of a body should be carried out in the conditions of a specialized repair truck at the disposal of which there is all necessary equipment.
In the presence of extensive damages of a body first of all it is necessary to be convinced, whether occurred shifts of elements of the body, capable to affect controllability of the car or to become the reason of the increased wear any of its knots.
In view of that (the cowl, wings, etc.) represent the majority of elements of a body of a detail to replace which it is possible separately, their replacement at serious damages is not represented expedient. As a rule, much more reasonably and cheaper it appears to find a suitable replaceable element, to find which it is possible not only in shops of spare parts, but also on automobile dumps that, naturally, allows to cut down essentially expenses.
